Due to the tremendous increase in the use of
electronic devices, ensuring Electromagnetic Compatibility (EMC) of a full
system in its early design phase is becoming one of the major technical
issues, especially for automotive manufacturers. Safe and reliable operation
must be guaranteed and legal requirements have to be satisfied. From both
car-makers and suppliers sides, the electromagnetic problems occur either when
integrating electronic devices in their operating environment (cross-coupling,
interference) or when dealing with the related EMC regulations (simulation of
radiating phenomena due to Common-Mode currents induced on attached cables).
As digital devices become smaller and perform at greater speeds, their
emissions increase, making a thorough understanding of Electromagnetic
Interference (EMI) essential for everyone in electrical engineering and design
today.

Design guidelines have been created to aid in
achieving EMC (Electromagnetic Compatibility) in automotive
electrical/electronic components and systems. None of the material presented
herein is new. On the contrary, it is based on well-established EMC measures
and techniques, and on specific automotive EMC experience accumulated over the
years within Ford Motor Company.
